I am very new to Linux and my Dreamplug(0901/0201 on back) will not boot into linux. I have jTag attached and working. Currently my printenv gives me:
baudrate=115200
bootcmd=setenv ethact egiga0; ${x_bootcmd_ethernet}; setenv ethact egiga1; ${x_bootcmd_ethernet}; ${x_bootcmd_usb}; ${x_bootcmd_kernel}; setenv bootargs ${x_bootargs} ${x_bootargs_root}; bootm 0x6400000;
bootdelay=3
eth1addr=02:50:43:07:d2:ca
ethact=egiga0
ethaddr=02:50:43:8d:2e:c8
stderr=serial
stdin=serial
stdout=serial
x_bootcmd_ethernet=ping 192.168.2.1
x_bootcmd_kernel=fatload usb 0 0x6400000 uImage
x_bootcmd_usb=usb start

Environment size: 473/4092 bytes


I have tried resetting many times with no improvement.

As I said, I am linux neophyte, can anyone help me get my dreamplug booting into Debian again? Thanks in advance.

If you have an SD card, you can format it, or the 1st partition as FAT.
Copy an uImage
https://dreamplug.googlecode.com/files/uImage_2.6.33.7
or
https://dreamplug.googlecode.com/files/uImage
to the SD, put the SD into the Dreamplug
do a
usb start
fatload usb 1 0x6400000 uImage
bootm 0x6400000

USB 0 is the internal micro SD & USB 1 is the SD slot
If that works the next step is to replace the uImage on the internal micro SD

Sorry, I missed it
At the Marvell prompt try:
setenv x_bootargs_root 'root=/dev/sda2 rootdelay=10'
saveenv
reset

Ok, let's manually enter the boot command & see if that helps:

setenv bootargs 'console=ttyS0,115200 root=/dev/sda2 rootdelay=10'
usb start
fatload usb 0 0x6400000 uImage
bootm 0x6400000

Ok, now I'm grasping at straws
manually enter the boot command & see if that helps:

setenv bootargs 'console=ttyS0,115200 root=/dev/sda2 rootdelay=10'
setenv mainlineLinux yes
setenv arcNumber 2097
usb start
fatload usb 0 0x6400000 uImage
bootm 0x6400000
